Do Bosch spark plugs need to be gapped?
Bosch Spark Plugs are pre-gapped at the factory. In most cases, that gap is indicated on the package. If the gap is adjustable and different from the gap specified by the engine manufacturer, it needs to be adjusted. For proper performance and exhaust emissions, the gap must be within ±0.004″ of the specified value.
What is better iridium or platinum spark plugs?
Iridium is said to be six times harder and eight times stronger than platinum with a 700° higher melting point. Iridium spark plugs have extremely fine electrodes while retaining excellent wear characteristics. Thanks to its strength, iridium spark plugs can last up to 25% longer than comparable platinum spark plugs.
Do you gap Bosch iridium plugs?
For most applications, the pre-set gap is correct. Note: Bosch OE Fine Wire Iridium, OE Fine Wire Double Platinum and OE Fine Wire Platinum are pre-gapped adjustment of gap could cause damage to the center electrode. See Spark Plug Gapping section.
